HENRY THOMAS, OF EAST HAM, ENGLAND.

HOLDER FOR TAPS, REAMERS, DIES, OR THE LIKE.

Application filed. January 22, 1920. Serial No. 353,331.

(GRANTEIY UNDER THE PROVISIONS OF THE A01 OF MARCH 3, 1921, 41 STAT. L, 1313.)

T 0 ct whom it may concern Be it known that I, HENRY THoMAs, a subject to the King of England, residing at 144: Clements Road, East Ham, in the county of Essex, England, have invented certain new and useful Improvements in Holders for Taps, Reamers, Dies, or the like, (for which I have filed application in England January 20, 1919, Patent No. 127,528 of 1919), of which the following is a specification.

This invention has for its object the provision of a device of the class named which shall be of improved construction and operation.

The invention is exemplified in the combination and arrangement of parts shown in the accompanying drawings and described in the following specification and it is more particularly pointed out in the appended claims.

In the drawings Y Fig. 1 is a plan view of one form of the device.

Fig. 2 is a similar view to Fig. 1 partly in section. v

Fig. 3 is an underside plan view of the same device.

Fig. 4 is a view in cross section at line 4-4 of Fig. 1. v

Fig. 5 is a perspective view of the rotary member.

Fig. 6 is a fragmentary view of another form of the device.

Fig. 7 is a similar view to Fig. 6, but in section.

Fig. 8 is an underside plan view of the device shown in Fig. 6.

Fig. 9 is a view in cross section at line 99 of Fig. 6.

Fig. 10 is a view in perspectiveof the rotary member employed in this construction.

Figs. 11 and 12 are views in plan and side elevation respectively of a modified form of tool, which can be used with the device illustrated in Figs. 6-10.

Fig. 13 is a fragmentary longitudinal section taken on Fig. 1 at right angles to the section Sl1OWI1 lI'l Fig. 4; and

Fig. 14 is a fragmentary longitudinal section taken on Fig. 6 at right angles to the section shown in Fig. 9.

In the construction illustrated in Figs:

1-5 the device comprises a pair of handle portions 1, 1 having a central boss portion 2. The boss portion 2 is provided with a circular recess 3 having a central projecting boss 4 and a right angle V shaped notch 5.

lVithin the recess 3 is placed the rotary member 6, which is provided with four right angle V shaped notches 7, 8, 9, and 10 of various sizes. The member 6 is provided with a central hole 11 adapted to fit over the boss 4: and it is further provided with a projecting portion 12 in order to facilitate turning it round on the boss 4;.

The parts are assembled as shown in the drawings, with any one of the notches 7, 8, 9, or 10 opposite to notch 5. When the desired notch has been moved into position the central member 6 can be held stationary by the set screw 13, which screws into the boss 4.

The shank of the tap or like tool enters the square recess formed by the co-operation of two notches as shown clearly by Fig. 2. In order that the shank of the tap or like tool shall not foul the set screw 13 the holder is placed on the tap, so that the tap projects from the opposite side to the set screw 13. In order to allow a square and even shoulder on the holder for making contact with the shoulder on the tap, the underside of the boss portion 2 is recessed as shown at 14 in Fig. 3, which serves to bring the face of the holder at this point level with the underside of the rotary member 6.

Referring to Figs. 6-12 the object of this modified construction is to provide a holder for taps or the like suitable for various sizes of taps and at the same time capable of holding a screw cutting plate such as is shown in Figs. 11 and 12.

In order to make this possible it is neces sary to dispense with the central boss 4 and to provide instead a central hole 15 leaving a flange 16 around the central recess 3.

- In this construction the rotary member has no central hole 11 as shown in Fig. 5, but is formed with a circumferential V shaped groove 17 as shown in Fig. 10.

In this construction also the notch 5 in the recess 3 may be made as shown in the drawing, that is, it does not extend completely through the thickness of the boss 2, but extends only as far as the flange 16.1

In this construction the parts are assembled as before, the projecting portion 12 on the rotaryinemben 6 forming a convenient means for rotating said member when re quired. The rotary member-6, however, is held in position by one or more radial setscrews 18 (three*are shown). 'These set screws 18 are shaped at their ends as shown at 19 to enter the groove 17.

In the construction shown in Figs. 610 a threadedholeQO may be provided to accommodate the set screw 18; when a rotary member such as shown in Fig. 5"is used with a holder as shown in Figs. 610.

It willbe seen that the construction'shown in Figs. 6-10 can conveniently" be used with a screw plate such as shown in Figs. 11 and 12, and such a screw plate may be providedwith grooves as shown at 21.

I claim:

l. A holder for tools comprising a boss member and'a member fitted therein and movable relative thereto, said boss member having a tixed notch therein and said movable member having a plurality of-notchcs of difl'erentsizes, the arrangement beingsuch that said movable member-may be moved into one of a number of positions with'a fixed n'otchin the boss member opposite to one of the notches in the movable member so as to enable the notches to'fit over the shank of the tool with the. faces of'the'fixed notch in said boss member engaging said tool, and means for retaining said movable member in "itsadj usted positions.

2. A tool holder comprising a member having an opemng therein, a second member fitted in 831d opening and movable relative to said first member, said first member, hav 111g a Vshaped notch therein the sidesoi.

which form Yfixed tool-engaging surfaces while said movable member has aplurality of"V shaped notches of different sizesar ranged to be moved SBlGClLlVdYlTltO registration withthe notch in saidfirst namedmemher to form tool sockets of various sizes.

3;A tool holder comprisingaf pair of members movable-relative to one another,

one of said members having a notch therein while the other of said members has a' plurality of notches otdilferent sizes to be brought selectivelvinto registration with the notches in said fir'st named member to provide tool sockets of various sizes and means for holding said movable. member. in fixedv positionr'elativeto said first named member with any one of the notches of said movable member in registration with the notch of saidlfirst named member.

a. A tool h o'lder -'compris'ing* handle member, a movable member fitted in an opening-in said'handle member, said members having notches therein arranged to be broughtintoregistration with one another brought into registration"with one another to provide sockets of varioussizes, said movable member having afgro'ov'ed periphery and means threaded in said handle member for engaging thegrooved 'peripherybf said movable member tdhbldsaid movable" member in fixed position in said handle member.

"6.A tool "holder comprising" a' handle member having an opening therein and a movable member fitted'insaid openin said members having notches arranged to "be brought into registration with one another to provide sockets of various sizes andmeans on said movable member to "facilitate adjustment thereof to bring said notches into registration withone another.

7. A tool holder comprising a handle 'member having a cylindricalopening therein a cylindrical plug 'rotatably' fitted'in said opening, said handle member having a" notch therein communicating with said'cylindrical opening, said cylindrical plug having afplu- "rality ofno'tches bf'diii'erent sizes in the periphery thereof, arranged tobe brought into "registration with 't'he notch in said handle member to provide sockets of'v'arioussizcs' meanson saidicylind'richl"plug by which it may be rotated to bring the various notcl'i'es therein intdreLristration with the notch in said handle member and means tor holding said cylindrical plug in adjusted positions, said handle member having a recessed portion to provide a"surface in a plane with the surface" otone end or" said cylindrical plug, adjacent "registering notches of said members. i
